FABRIC TREATMENT.

The invention relates to treatment of fabric to render the sametransparent or translucent for use as window lights, for instance totake the place of common glass in hot houses, chicken houses and otherplaces where applicable, and has for its object to provide a continuousprocess of treatment whereby a roll of fabric may be passed submergedthrough a bath of beeswax yellow,

1 paraffin and petrolatum vellow which will coat the fabric and renderthe same translucent.

A. further object is to provide scraping bars engaging opposite sides ofthe fabric as it leaves the bath which will smooth the coating andscrape excess material therefrom. The bath is preferably in proportionsof fifty parts of paraffin to five parts of bees wax yellow and one partpetrolatum yellow.

A further object is to provide heating elements under the tank and meanswhereby the material, after the coating operation may be wound onto aroll for shipping and storage purposes.

With the above and other objects in view the invention resides in thecombination and arrangement of parts as hereinafter set forth, shown inthe drawing, described and claimed, it being understood that changes inthe precise embodiment of the invention may be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawing, the single figure shows a longitudinal sectional viewthrough the tank,

and the fabric roll in position whereby the strip of fabric may bepassed through the 7 bath in the tank, and in which figure the numeral 1designates the frame of the device and 2 the tank. The material 3 in thetank is formed from a mixture of fifty arts of paraffin to five parts ofbeeswax yel ow and one part of petrolatum yellow. The paraflin suppliesthe necessary body of'the fabric and the beeswax yellow and petrolatumyellow give the same elasticity and prevent cracking, and theproportions set forthhave been found to give the best results. Disposedbeneath the tank 2 are gas burners 4, the flame from which heats thetank in which theingredients are placed and mixed and the material 3 isreferably maintained at a temperature o 50 to 60 degrees. Disposedwithin the tank 2 adjacent the bottom thereof and adjacent the ends ofthe bottom are rollers 5 under which the strip of fabric 6 passes. Thestrip of fabric 6 is unwound from a roll 7 and moves in the direction ofthe arrow a over the upper side 8 of the tank 2 at one end thereof, andthence downwardly into the coating material 3 under the rollers 5, andthence upwardly over the upper edge of the scrapin strip 9. The strip offabric then passes downwardly and under the scraping strip 10,whichscrapes the upper surface ,of the strip of fabric simultaneouslywith the scraping of the under side of the strip of fabric by thescraping member 9. The scraping operation takes place after the strip offabric passes from the bath, consequently bothsidesare thoroughlysmoothed and scraped. The accumulating roll 11, which is provided with ahandle member 12 is located a substantial distance from the bath,consequently the material will harden on the fabric before it isaccumulated on the roll 11, however after the accumulating operation theroll 11 is in condition to be shipped or stored. It has been found thatfabric so treated when used in connection with and as a window light itis waterproof and weather proof,'prevents cold from entering a buildingor house, also radiates heat from the suns rays, consequently suppliesheat to the interior of the house and the radiating qualitiesthereofhave been found to exceed that of glass. It has also been found that ittransmits ultra violet rays which is conducive to the health of animals,poultry, plates and human beings.

The invention having been set forth what is claimed as new and useful is1.-A composition of matter adapted to render fabric translucentcomprising a mixture of paraffin, beeswax and pctrolatum in suchproportions that when applied to a fabric it will not crack and will befree of pin holes. 2. A composition of matter adapted to render fabrictranslucent comprising a mixture of fifty parts of paraffin, five partsbeeswax, and one part petrolaliuu.

In testimony whereof we hereunto afiix our signatures.
